Irving Moffat Cleghorn (August 22, 1863[1] – November 14, 1929[2]) was a politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1927 to 1929, as a member of the Manitoba Liberal Party.[3]
Born in Moffat, Scotland, Cleghorn came to Canada with his family at the age of four. They settled in Wingham, Ontario. He studied medicine at the Manitoba Medical College[1] and set up practice in Belmont, Manitoba in 1891, moving to Baldur the following year. Cleghorn also operated a pharmacy in Baldur from 1903 until 1929.[4] He was elected to the Manitoba legislature in the 1927 provincial election, defeating Progressive incumbent Charles Cannon[3] by 84 votes.
The election was won by the Progressive Party. Cleghorn served on the opposition benches for the next two years[3] and died at home in Baldur while still a member of the legislature.[2]
